Hydroelectric Energy
By Daniel Kolano, Matt Osten, Nisha Rao, and Anna Sproule
• Mountainous countries; Switzerland and New Zealand, hydroelectric power provides more than half of the energy the county needs
• Hoover Dam(Boulder Dam)-built in 1931. Opened in 1936-costed $49 million to build-height: 726.4ft.-length: 1,244ft.
How a Dam Works
Facts about Hydroelectric energy
• Dams built to trap water• Usually built in a valley where there is
a lake• Dams: thick at bottom; thin at top• hydroelectric power stations may
produce a large deal of power at a cheap price• Generators generate power
How it works...
Advantages-• It needs no fuel to operate and no waste is
produced• It is cheap to fix and operate• Can produce a lot of energyDisadvantages-• It depends on waves so there could be a lot of
energy or little to nothing• It must be place where strong waves will
mostly occur• It also must withstand harsh weather
Advantages and Disadvantages
• Good AND Bad• Good- There is no waste or pollution- Uses the never-ending water cycle• Bad- Expensive- They flood the area upstream- Can affect the water quality
downstream which can then affect the plantlife
Is the Energy Good for the Environment?
• Hydroelectricity is renewable- It uses the water cycle, and the water
cycle is never-ending.
Is the Energy Renewable or Nonrenewable?
Even though hydroelectric energy is the largest renewable resource, Pittsburgh is not the ideal place because our rivers are not big enough for a dam to power the energy.
Hydroelectric Energy In Pittsburgh
The future of hydroelectric energy seems plentiful in our opinion. Since we will have the same amount of water in one hundred years, that water could be used to power many more than what we have now.
